Detailed Description

template<typename T, Component C>
class core::ComponentManager< T, C >

ComponentManager is a class that owns Component in a contiguous array. Component indexing is done with an Entity.

Template Parameters

T	type of the component
C	unique binary flag of the component. This will be set in the EntityMask of the EntityManager when added.

AddComponent()

template<typename T , Component C>

void core::ComponentManager< T, C >::AddComponent ( Entity  entity )

virtual

AddComponent is a method that sets the flag C in the EntityManager and resize if need the components_ array.

Parameters

entity

will have its flag C added in EntityManager

Reimplemented in core::ScaleManager.

Here is the caller graph for this function:

CopyAllComponents()

template<typename T , Component C>

void core::ComponentManager< T, C >::CopyAllComponents

(

const std::vector< T > &

components

)

CopyAllComponents is a method that changes the internal components array by copying a newly provided one. It is used by the RollbackManager when reverting the current game world data with the last validated game world data.

Parameters

components

is the new component array to be copy instead of the old components array

GetAllComponents()

template<typename T , Component C>

const std::vector< T > & core::ComponentManager< T, C >::GetAllComponents

GetAllComponents is a method that returns the internal array of components.

Returns

the internal array of components

GetComponent() [1/2]

template<typename T , Component C>

T & core::ComponentManager< T, C >::GetComponent

(

Entity

entity

)

GetComponent is a method that gets a reference to a Component given the Entity.

Parameters

entity

is the one that we want the Component of.

Returns

the reference to the Component of Entity entity.

GetComponent() [2/2]

template<typename T , Component C>

const T & core::ComponentManager< T, C >::GetComponent

(

Entity

entity

)

const

GetComponent is a method that gets a constant reference to a Component given the Entity.

Parameters

entity

is the one that we want the Component of.

Returns

the constant reference to the Component of Entity entity.

RemoveComponent()

template<typename T , Component C>

void core::ComponentManager< T, C >::RemoveComponent ( Entity  entity )

virtual

RemoveComponent is a method that unsets the flag C in the EntityManager.

Parameters

entity

will have its flag C removed

SetComponent()

template<typename T , Component C>

void core::ComponentManager< T, C >::SetComponent	(	Entity	entity,
		const T &	value
	)

SetComponent is a method that sets a new value of the Component of an Entity.

Parameters

entity	will have its component set.
value	is the new value that will be set.
